I made a typo when booking a reservation from SEA to SAN. I just noticed that my BA Exec number is not correct but cannot see a means of doing this on line, I am flying F so the benefits are already there but I wish to get the Points and Avios involved. Is there a way of doing this online or must I ring up, or could this be done at the airport? This ticket is a cash and not a redemption booking.

I am flying four legs with Alaska - the other three are correct. This is not happening until July - so I have time,

I am sorry in advance if this has already been covered but on Google the last time that I could see was 2008 - things might have changed.

Many Thanks for any help
